THYROLAR or liotrix is not natural desiccated thyroid. It is synthetic T3 (L-triiodothyronine) and synthetic T4 (levothyroxine sodium) with a ratio of four parts T4 to one part T3. It contains no T2, T1 or calcitonin. The tablets need to be kept refrigerated.

INGREDIENT EXPLANATIONS:

Microcrystalline Cellulose synthetically derived fibre base (similar to plant-derived). It is typically used as a filler in tablets to provide volume and bulk.

Dicalcium Phosphate derived from a mined ore. It is typically used as a binder in tablets to hold all the ingredients during compression.

Colloidal Silicon Dioxide derived from a mined ore. Typically used as a natural desiccant in tablets to provide a barrier from moisture and humidity.

Sodium Starch Glycolate Synthetically derived starch molecule (similar to potato starch). It is typically used as a disintegrating agent in tablets to aid in proper disintegration of the tablet in the stomach.

Magnesium Stearate Derived from a vegetable source (typically palm oil). It is typically used as a lubricating agent in tablets to aid in proper compression of the tablet.

Hydroxypropyl Methylcellulose Derived from a plant cellulose base (typically cotton blend or wood pulp). It is typically used as a granulating agent in tablets to provide bulk and density to the tablet for proper compression, as well as part of a clear coating solution (with PEG).

Polysorbate 80 An inactive water soluable emulsifying agent which blends the ingredients of mixtures and prevents separating.

Stearic Acid derived from a vegetable source (typically palm oil). It is typically used as a binder in tablets to hold all the ingredients during compression).

Carnauba Wax derived from the pores of the leaves of the Brazilian wax palm tree. It is used in the final stage in tablet coating to provide a complete seal.

Polyethylene Glycol (PEG) Synthetically derived, water-soluble, waxy solid. It is used with Hydroxypropyl Methylcellulose as part of the clear coating solution.

Lactose Monohydrate Present in traceable amounts as part of Thyroid USP (diluent)
